Description

Technical Field

[0001] This application relates to the field of building engineering monitoring technology, specifically a monitoring instrument for foundation pit engineering of high-rise buildings. Background Technology

[0002] In the foundation pit engineering of high-rise buildings, ensuring construction safety and project quality is of paramount importance. Real-time monitoring of the foundation pit's displacement and pressure is a crucial step in assessing its stability and safety. However, current monitoring technologies have many limitations in achieving comprehensive and accurate monitoring.

[0003] Existing foundation pit monitoring technologies rely on sensors located at single, fixed positions, which cannot provide comprehensive monitoring of the pit's interior. Furthermore, monitoring devices typically cannot be adaptively adjusted to the actual width of the pit, resulting in inflexible monitoring point placement and an inability to achieve multi-point, multi-dimensional real-time monitoring. This leads to incomplete monitoring data and impacts the accuracy of construction decisions. Therefore, a foundation pit engineering monitoring device is needed that can be adjusted according to different pit widths and achieve multi-point, multi-dimensional real-time monitoring. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a monitoring instrument for foundation pit engineering in high-rise buildings, which has the advantages of enabling real-time monitoring of multiple points and dimensions, and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a monitoring instrument for foundation pit engineering of high-rise buildings, comprising a column, wherein the column has equidistantly arranged detection chambers inside, and two symmetrical lead screws are rotatably connected to the inner wall of each detection chamber. Each lead screw has a movable seat on its outer side, and a detection rod is slidably connected to the inner wall of the movable seat, with the outer surface of the detection rod slidably connected to the inner wall of the column. A pressure sensor is fixedly embedded in the upper surface of the movable seat, and the sensing end of the pressure sensor is in direct contact with the outer surface of the detection rod. A mounting plate is fixedly connected to one end of the detection rod, and a displacement sensor is fixedly installed on the side of the mounting plate. A tension spring is fixedly connected to the side of the mounting plate, and one end of the tension spring is fixedly connected to the outer surface of the movable seat. An abutment plate is fixedly connected to the other end of the detection rod. A controller is fixedly installed on the upper surface of the column, and a control tube is fixedly connected to the inner wall of the column. A transmission cable is fixedly installed at the bottom of the controller, and the transmission cable is located inside the control tube. A base is fixedly connected to the bottom surface of the column, and four rectangular array horizontal adjustment components are provided at the bottom of the base.

[0006] The above scheme, through the interaction between the detection chamber and the detection rod, enables real-time monitoring of different locations and depths of the foundation pit, thereby providing a more comprehensive understanding of the pit's stability and safety. Furthermore, the coordinated action of the pressure sensor, mounting plate, displacement sensor, tension spring, and abutment plate enriches the monitoring data, helping workers better grasp the specific conditions within the foundation pit. This achieves multi-point, multi-dimensional real-time monitoring, improving the comprehensiveness and accuracy of the monitoring data. Subsequently, the leveling component ensures the column remains level within the deep foundation pit, thus maintaining a horizontal state during installation and further enhancing the accuracy of the monitoring data.

[0007] Furthermore, each of the movable seats is provided with a drive assembly on its exterior. The drive assembly includes a servo motor, which is fixedly connected to the upper surface of the movable seat. A second gear is fixedly connected to the output end of the servo motor. An internally threaded tube is rotatably connected to the inner wall of the movable seat. A first gear is fixedly connected to the outer surface of the internally threaded tube, and the inner wall of the internally threaded tube is threadedly connected to the outer surface of the lead screw. The first gear and the second gear mesh with each other.

[0008] The above scheme, through the coordinated action of the lead screw, internal threaded tube, first gear, servo motor, and second gear, allows for adjustment of the position of the moving seat, thereby driving the detection rod to adjust. This allows for adjustment based on the width of the deep foundation pit, thus improving the practicality of the monitoring device.

[0009] Furthermore, each of the detection chambers has two symmetrical movable seats on its inner wall, and the outer surface of each movable seat is slidably connected to the inner wall of the guide groove.

[0010] The above solution, by setting the guide groove, can limit and guide the movement of the moving seat, ensuring that the moving seat drives the detection rod to move stably and accurately.

[0011] Furthermore, the outer surface of the control tube is provided with a plurality of equally spaced slots, the outer surface of the control tube extends through a plurality of detection cavities and to the upper surface of the column, and the displacement sensor and the pressure sensor are electrically connected to the transmission cable via cables, the cables of which can pass through the slots provided in the control tube.

[0012] The above scheme, by setting up a control tube, connects the internal transmission cable to multiple sensors through the transmission line, thereby forming an integrated data transmission line, uniformly controlling the sensor signals of each detection cavity, realizing centralized data processing and real-time feedback, and simplifying wiring complexity.

[0013] Furthermore, a mounting cavity is provided on the bottom surface of the column, and a level is fixedly installed on the inner wall of the mounting cavity. The level is electrically connected to the controller through the transmission cable.

[0014] The above scheme, by setting up a level, can monitor the levelness of the column in real time, and with the help of the leveling adjustment component, can ensure that the column is in a level state.

[0015] Furthermore, the horizontal adjustment component includes a component cavity, the inner wall of which is formed on the bottom surface of the base, and a hydraulic telescopic rod is fixedly connected to the inner wall of the component cavity. The hydraulic telescopic rod and the controller are electrically connected, and the output end of the hydraulic telescopic rod is fixedly connected to the base plate.

[0016] The above solution utilizes the interaction between the hydraulic telescopic rod and the base plate to move the base plate, thereby adjusting the level of the column. This ensures that the column remains level during installation and improves the accuracy of monitoring data.

[0017] Furthermore, two lifting lugs are fixedly connected to the upper surface of the column.

[0018] The above scheme, by setting up lifting lugs, facilitates the hoisting and transportation of the column, thereby improving the installation efficiency of the device.

[0019] Furthermore, a protective box is fixedly connected to the upper surface of the column by threads, and the controller is located inside the protective box.

[0020] The above solution, by setting up a protective box, can shield and protect the controller, thereby ensuring the safety of the controller in the deep foundation pit.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

One end of the detection rod 5 is fixedly connected to a mounting plate 7, and a displacement sensor 8 is fixedly mounted on the side of the mounting plate 7. The instrument is configured to detect... The interaction between cavity 2 and detection rod 5 enables real-time monitoring of different positions and depths of the foundation pit, thereby providing a more comprehensive understanding of the stability and safety of the foundation pit. Furthermore, the cooperation between pressure sensor 6, mounting plate 7, displacement sensor 8, tension spring 9, and abutment plate 10 enriches the monitoring data, helping workers to better grasp the specific situation inside the foundation pit. This enables multi-point, multi-dimensional real-time monitoring, improving the comprehensiveness and accuracy of the monitoring data. Subsequently, the horizontal adjustment component ensures that column 1 is level within the deep foundation pit, thereby ensuring that column 1 remains level during installation and improving the accuracy of the monitoring data.

[0032] Please see Figure 2 , Figure 3 and Figure 4A tension spring 9 is fixedly connected to the side of the mounting plate 7, and one end of the tension spring 9 is fixedly connected to the outer surface of the movable seat 4. The other end of the detection rod 5 is fixedly connected to the abutment plate 10. A controller 16 is fixedly installed on the upper surface of the column 1. The controller 16 can collect data from all sensors in the device in real time and derive data according to the internal algorithm. At this time, the data of the controller 16 can be transmitted to the display outside the deep pit for easy viewing by the staff. A control tube 17 is fixedly connected to the inner wall of the column 1. A transmission cable 24 is fixedly installed at the bottom of the controller 16 and is located inside the control tube 17. A base 20 is fixedly connected to the bottom surface of the column 1. The bottom of the base 20 is provided with four rectangular array horizontal adjustment components. The four horizontal adjustment components can adjust the levelness of the column 1. To ensure the levelness of column 1 during installation, each movable seat 4 is equipped with a drive assembly. The drive assembly includes a servo motor 13, which is fixedly connected to the upper surface of the movable seat 4. The output end of the servo motor 13 is fixedly connected to a second gear 14.

By setting the cooperation between the lead screw 3, the internally threaded tube 11, the first gear 12, the servo motor 13, and the second gear 14, the position of the movable seat 4 can be adjusted, thereby driving the detection rod 5 to be adjusted. This can be adjusted according to the width of the deep foundation pit, thereby improving the practicality of the monitoring device.

[0033] Please see Figure 2 and Figure 4 Each detection cavity 2 has two symmetrical movable seats 4 on its inner wall. The outer surface of each movable seat 4 is slidably connected to the inner wall of the guide groove 15. By setting the guide groove 15, the movement of the movable seat 4 can be limited and guided, ensuring that the movable seat 4 drives the detection rod 5 to move stably and accurately. The outer surface of the control tube 17 has multiple equally spaced holes and slots. The outer surface of the control tube 17 passes through multiple detection cavities 2 and extends to the upper surface of the column 1. The displacement sensor 8 and the pressure sensor 6 are electrically connected to the transmission cable 24 through cables. The cables can pass through the holes and slots of the control tube 17. By setting the control tube 17, the internal transmission cable 24 is connected to multiple sensors through the transmission line, thereby forming an integrated data transmission line, uniformly controlling the sensor signals of each detection cavity 2, realizing centralized data processing and real-time feedback, and simplifying the wiring complexity.

[0034] Please see Figure 2 and Figure 5A mounting cavity 18 is provided on the bottom surface of the column 1. A level 19 is fixedly installed on the inner wall of the mounting cavity 18. The level 19 is electrically connected to the controller 16 via a transmission cable 24. By setting the level 19, the levelness of the column 1 can be monitored in real time. With the help of the level adjustment component, the column 1 can be ensured to be in a level state. The level adjustment component includes a component cavity 21. The inner wall of the component cavity 21 is opened on the bottom surface of the base 20. A hydraulic telescopic rod 22 is fixedly connected to the inner wall of the component cavity 21. The hydraulic telescopic rod 22 is electrically connected to the controller 16. The output end of the hydraulic telescopic rod 22 is fixedly connected to the base plate 23. By setting the hydraulic telescopic rod 22... 2. The interaction between the base plates 23 allows the base plates 23 to move, thereby adjusting the level of the column 1. This ensures that the column 1 remains level during installation, improving the accuracy of monitoring data. Two lifting lugs 25 are fixedly connected to the upper surface of the column 1. The lifting lugs 25 facilitate the hoisting and transportation of the column 1, thereby improving the installation efficiency of the device. A protective box 26 is fixedly connected to the upper surface of the column 1 by threads. The controller 16 is located inside the protective box 26. The protective box 26 provides shielding and protection for the controller 16, ensuring its safety in the deep foundation pit.

[0035] This embodiment of a foundation pit monitoring instrument for high-rise buildings enables real-time monitoring of different locations and depths of the foundation pit through the interaction between the detection chamber 2 and the detection rod 5. This allows for a more comprehensive understanding of the stability and safety of the foundation pit. Furthermore, the coordinated action of the pressure sensor 6, mounting plate 7, displacement sensor 8, tension spring 9, and abutment plate 10 enriches the monitoring data, helping workers better grasp the specific conditions within the foundation pit. This achieves multi-point, multi-dimensional real-time monitoring, improving the comprehensiveness and accuracy of the monitoring data. Subsequently, the horizontal adjustment component ensures that the column 1 is level within the deep foundation pit, thereby ensuring that the column 1 remains level during installation and improving the accuracy of the monitoring data.

[0036] The working principle of the above embodiment is as follows: First, the column 1 is placed inside the deep foundation pit. Then, after the base 20 contacts the bottom of the deep foundation pit, the level 19 can monitor the level of the column 1. Then, the controller 16 can collect the data monitored by the level 19 in real time and control the hydraulic telescopic rod 22 in the four sets of leveling components. Then, the hydraulic telescopic rod 22 pushes the base plate 23 to move, thereby adjusting the level of the column 1. Then, the servo motor 13 is started to drive the second gear 14 to rotate. The meshing with the first gear 12 can drive the internal thread tube 11 to rotate, thereby driving the moving seat 4 to move on the surface of the lead screw 3. Then, while the moving seat 4 moves, the detection rod 5 can move. Furthermore, the detection rod 5 is in a reset state under the tension of the tension spring 9. At this time, the movement of the movable seat 4 can drive the detection rod 5 to move until the abutment plate 10 contacts the side wall of the deep foundation pit. This allows the width of the detection rod 5 outside the column 1 to adapt to deep foundation pits of different widths. At this time, the detection rods 5 inside multiple detection chambers 2 can be realized, enabling real-time monitoring of multiple points and dimensions, improving the comprehensiveness and accuracy of monitoring data. Finally, when the deep foundation pit is displaced, it can drive the detection rod 5 to move. At this time, the pressure sensor 6 and the displacement sensor 8 can monitor the movement and pressure of the detection rod 5. The data from both can further help the staff to better understand the specific situation inside the foundation pit.
